When you set up a European office or a virtual office in Portugal, one of the first questions you might ask is: Do I really need an accountant? After all, if your business is small, remote, and mostly online, it might seem like an unnecessary expense.

But in Portugal, having a certified accountant is not just good practice — for most businesses, it’s a legal requirement. Whether you’re running a single-person consultancy from abroad or managing a growing online store from your Portuguese office, an accountant plays a key role in keeping you compliant and avoiding costly mistakes.

At European Virtual Office, we provide more than just an address. We can connect you with experienced accountants who understand the needs of foreign entrepreneurs, so you never have to worry about tax deadlines or Portuguese bureaucracy.


Why an accountant is often mandatory in Portugal

Portuguese business law requires that almost all companies — even micro and small businesses — have a certified accountant (Contabilista Certificado). Their role is to:

  • Prepare and submit monthly or quarterly VAT returns.
  • File annual corporate income tax reports.
  • Maintain accurate and compliant accounting records.
  • Represent you in dealings with the Portuguese Tax Authority.

If you skip this step, you risk fines, penalties, and, in some cases, suspension of your tax number.


Even a virtual office needs accounting

Some people think that because their virtual office in Portugal isn’t a physical shop or factory, they can skip accounting. This is a common misunderstanding.

If your Portuguese-registered business issues invoices, pays suppliers, or receives payments, it has tax obligations — even if all your clients are abroad. The authorities don’t care whether your office is physical or virtual; they care whether you comply with the law.


Common tasks your accountant will handle

A good accountant in Portugal will:

  1. Register your company for taxes and VAT (if applicable).
  2. Keep your accounts updated every month.
  3. Prepare and submit official reports to the tax office.
  4. Advise on deductions and compliance so you pay only what you owe.
  5. Communicate with the authorities on your behalf, so you don’t have to deal with government forms in Portuguese.

Why using our accountant network is smarter

While you could try to find an accountant on your own, foreign entrepreneurs often face challenges:

  • Language barriers.
  • Accountants unfamiliar with international or online business models.
  • Difficulty managing everything remotely.

Through European Virtual Office, you get access to certified accountants who:

  • Are experienced with EU and non-EU clients.
  • Understand the needs of small businesses and start-ups.
  • Communicate in English (and sometimes other languages).
  • Integrate seamlessly with our virtual office and company registration services.

Can I start without an accountant?

If you’re a sole trader (ENI) with no employees, you may not legally need an accountant at first, but in practice, most still hire one. Why?

  • Portuguese tax rules are complex.
  • Mistakes can lead to large fines.
  • An accountant can often save you more money than they cost.

How our service works

When you register your business with European Virtual Office, we can:

  1. Set up your Portuguese virtual office address.

  3. Introduce you to a certified accountant who will manage all your filings.
  4. Keep you compliant year-round, so you can focus on running your business.

What we need from you

That’s it — from there, we handle all the setup and coordination.
